The invention provides a heat dissipation device for an upper platform of a stamping machine. The heat dissipation device for the upper platform of the stamping machine comprises a main body, a firstconnecting plate and a second connecting plate; the main body comprises a heating assembly, a heat dissipation assembly and an upper platform, the heat dissipation assembly is formed by combining a plurality of heat dissipation components, heat dissipation units are provided with air grooves, the heating assembly and the heat dissipation assembly are both rectangular, the heat dissipation assemblyis arranged above the heating assembly, the upper platform is installed above the heat dissipation assembly, and the first connecting plate and the second connecting plate are installed on the two opposite sides of the main body respectively. The heat dissipation device has the advantages that the heat dissipation assembly is composed of a plurality of independent heat dissipation components, sothat the overall thermal expansion amount is reduced; and the heat dissipation efficiency is improved by ventilating the air grooves in a heat dissipation plate, so that the requirement for the heat expansion of a large-format gold stamping equipment can be better met.
Description
technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for an upper platform of a bronzing machine. Background technique [0002] With the rapid development of the printing and packaging industry, the market has higher and higher requirements for the automation of post-press processing equipment. The pursuit of high-speed and precise processing equipment to improve production efficiency and occupy the market is the market demand and the development of post-press equipment. trend. The hot stamping machine needs to heat the gold foil during the hot stamping process, and the heated gold foil is firmly printed on the paper to complete the hot stamping. The heating device is installed on the upper platform of the machine. Heat will be generated during the heating process, and the heat will be conducted to the upper platform to cause thermal expansion of the upper platform. The thermal expansion of the upper platform ...
